Tuple ¶

A tuple is just like a list except the content cannot change, meaning I cannot do any mutation (i.e., replace, append, or delete).

In [14]:

in_my_closed_pocket = (21, False, None, "apple", 3.14)
print(in_my_closed_pocket)

in_my_closed_pocket = (21, False, None, "apple", 3.14) print(in_my_closed_pocket)

(21, False, None, 'apple', 3.14)

In [15]:

print(in_my_closed_pocket[3])

print(in_my_closed_pocket[3])

apple

In [16]:

in_my_closed_pocket.append("wallet")

in_my_closed_pocket.append("wallet")

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Cell In[16], line 1
----> 1 in_my_closed_pocket.append("wallet")

AttributeError: 'tuple' object has no attribute 'append'

In [17]:

del in_my_closed_pocket[3]

del in_my_closed_pocket[3]

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
Cell In[17], line 1
----> 1 del in_my_closed_pocket[3]

TypeError: 'tuple' object doesn't support item deletion

So why would you want to use a tuple instead of a list?

• If you need a collection of items that should not be changed or modified throughout the program, using a tuple provides immutability. This prevents accidental modifications and ensures data consistency.
• Tuples are generally more memory-efficient than lists because of their immutability. If your data does not need to change, using a tuple can result in better performance.
